When I started inspecting 17 years ago I started out using the Dell Axum 5. Went through a few of those then I stepped up to the HP IPAQ 210 then 211. Then a few years after that my inspection software stopped supporting the mobile software for the OSs on those machines in exchange for the mobile phone systems. I started with a Note 2, then Note 5, and now using a Note 9. My next phone will be the Note XX.
I use 3D software.
